afs: Eliminate the address pointer from the address list cursor
Eliminate the address pointer from the address list cursor as it's redundant (ac->addrs[ac->index] can be used to find the same address) and address lists must be replaced rather than being rearranged, so is of limited value. Signed-off-by: David Howells <dhowells@redhat.com>
